I have a problem with a microphone TLM 193 S/N 01178
And this problem seem to come from IC2 on the electronic circuit.
After I had talk to the distributor Neumann in Canada (Sennheiser Canada )
They have tell me that they don’t have any schematic advalable.
And that IC2 and IC1 are not advalable.

Only the complete electronic PCB assemble his advalable at the price of $735.00 ca.
I am very desapointed that the IC2 is not advalable and it is unacceptable to change the complete electronic circuit at the coast of $735.00ca.

I will be very sad to trash the microphone.

Do you have any solution for me?
Thank
